For some reason my computer is been freezing lately, wow is lagging like crazy and counter strike just froze after a while of playing. I tried many Registry cleaners, scan my computer for virus, spyware, malware.I have defrag my computer, update everything. I checked over heating and dust seems fine plus i put my fan at its fastest pace so it wont over heat. This started to happen like a week ago. Here a list of software I use to scaning for anything.I think is hardware failure or something to do with my power supply.
Zone Alarm Extreme security my firewall/ anti virus/ anti spyware
Advance system care pro Registry cleaner/anti spyware/cleaner
Malwarebytes anti malware

As of two months ago nearly all the rar files (r01,r02,r03,etc) I download that are between 40mb-100mb never extract properly.
These are the error messages I get

With 7z – "CRC failed in ‘name of file’. File is broken"
With Winrar – "Packed data CRC failed in ‘name of file’. The volume is corrupt" with WinRAR (tried several versions)

Now I know you can set winrar to ignore the message and continue. But I need to know, is this due to some sort of hardware failure?
I ran memtest 86+ for 14 hours with no errors. Possibly my harddrive is going? (despite not finding any errors with hd diagnostic software)

So then I decided to move the exact same files over to my old computer. They extract perfectly. So its obviously not caused by the download source.

The strange thing is I can extract 1gig rar files perfectly. But if the 1 gig extracts into smaller rar files I cannot extract those.

I already replaced the RAM with new memory. To no avail.

If this helps my specs are :
Windows 7 operating system (tried it on my dual-boot Windows XP SP3 as well)
ASUS Striker Extreme motherboard
8 Gigs Crucial Ballistix DDR2
500gb Seagate Barracuda 7200.10 drive
1tb Western Digital external drive
ATI Radeon 2900xt graphics card

Oh, and i’ve formatted my harddrive twice since these errors. I’m hoping its something as cheap as replacing the CMOS battery. 😛

Solidus – I know the files aren’t corrupt due to the download itself because the exact same files extract perfect when I move them to a different computer.
Oh and i’ve tried re-downloading. No luck.

I have to turn my computer on and off at least a half dozen times before I can get to my desktop. Usually about 3 times before I get the screen telling me that windows was shut down abnormally and giving me several other starting options. At this point, I choose safe mode and sometimes it frreezes midway through loading the drivers and always freezes after loading all the drivers.
With every cycle, the process goes just a little farther with safe mode finally loading or sometimes, I try to let windows start normally with that working as well.
No matter what, whenever I get to a point where I can restart the computer, it's fine from there on. Never any problem on restart. Might I be experiencing some sort of hardware failure?
